Just pick some up last week, looking forward to using it ,I'll detailing a 93 corvette this weekend . Just one question is it a must to use sealant . I have megs21, but with the cure time 12 hrs . It's more of a either one or the other, I will have the car for only 4to 5 hrs max. any ideas . I bought the Souveran for this car & my own avalance both are Forest Green..The vette is rough shape so, I figure i will take me at least 3 hrs to get prepped for wax or sealant.
